I heard on NPR that she hit unexpectedly high currents which took her off course. With an event this long she'd go through every available source of energy no matter what she eats. When she reaches the end she'd be drawing energy from her muscles, basicly eating them

There's no room for error or to go off course and "oh, I'll just swim another 20 miles or so ..."

Amazing effort! Can we get her here to post to the "Is there anyone here over 60?" thread? Has anyone read her training regime? Astounding.
